Just 9% of the millions of tonnes of fish caught by China’s giant fishing fleet in African and other international waters is officially reported to the UN, say researchers using a new way to estimate the size and value of catches.
Fisheries experts have long considered that the catches reported by China to the UN’s Food and Agriculture Organization (UNFAO) are low but the scale of the possible deception shocked the authors.
“The study shows the extent of the looting of Africa, where so many people depend on seafood for basic protein. We need to know how many fish have been taken from the ocean in order to figure out what we can catch in the future,” says Daniel Pauly, at the University of British Columbia (UBC). “Countries need to realize the importance of accurately recording and reporting their catches and step up to the plate, or there will be no fish left for our children.”
The alleged gross misrepresentation of the official Chinese catch suggests that many countries are being systematically cheated, leaving them unable to devise effective management plans to conserve stocks. The long term implications for food security could be severe because many millions of people in developing countries depend on fish both for their livelihoods and for their diets.
But a spokesman for the UNFAO, the agency that keeps track of global fisheries catches, disputed the new figures. “The estimates in this paper of Chinese catches off west Africa are far too high.”

In their new study, scientists at UBC estimate that China’s “distant water” fleet of 3,400 vessels catches 4.1m tonnes of fish every year, worth $11.5bn, from the coastal waters of 93 countries. But the Chinese government, says the report, tells the UNFAO that its vessels only took an average of 368,000 tonnes a year from 2000-2011.
The team of 20 researchers calculated the number of Chinese vessels fishing in international waters by consulting news reports, online articles and local fishery experts and estimated that nearly 75% of all the fish caught by Chinese vessels came from African waters, with almost 3m tonnes a year from west Africa.
According to the UNFAO, the west African coast has some of the world’s most abundant fishing grounds, but almost all are fully or over-exploited by international fishing fleets.
The FAO spokesman said the estimated 3m tonne take by China off west Africa was on the same scale as the total catch of all 22 west African coastal states and 38 foreign nations fishing in the region in combined. He noted that unregulated catches are by definition unreported but said the “best” estimate for these was less than 560,000 tonnes a year.
If Chinese vessels are taking far more fish than suspected, it would mean that many poor countries are losing tens of millions of dollars, having signed contracts with Chinese companies to catch far fewer fish. However, the study does not try to estimate the amount of illegal fish caught by Chinese vessels.
According to Greenpeace, sub-Saharan Africa is now the only region on earth where per capita fish consumption is falling, largely because foreign fishing fleets have removed so much fish.
Public pressure both in Europe and in developing countries has forced European fleets to stop fishing in some west African coastal waters, but Chinese vessels have moved in, to the consternation of local fishing fleets.
“Chinese agreements are generally the most private and secretive and are often only known to a few individuals within a host country’s ministry,” says the report.
“China hasn’t been forthcoming about its fisheries catches,” says Dirk Zeller, a co-author of the study. “While not reporting catches doesn’t necessarily mean the fishing is illegal—there could be agreements between these countries and China that allow fishing—we simply don’t know for sure as this information just isn’t available.”
The authors estimated that 345 Chinese ocean-going vessels fish African waters with several thousand others working in Pacific waters. Some of the fish is sold on the international market but much is returned to China. The only large regions of the world where Chinese distant water vessels do not operate are the Arctic, the Caribbean and the coasts of North America and Europe.

Fish unable to pass through dams in U.S. presents ‘cautionary tale’ for developing world
(01/17/2013) Dams create a largely impenetrable barrier for fish even when the dams were installed with specially-built passages, according to a new study in Conservation Letters. The scientists found that migrating fish largely failed to use the passages in the U.S., resulting in far fewer moving through the state-of-the-art hydroelectric dams than had been promised. The researchers say that their findings are a “cautionary tale” for developing nations.

Saving manta rays from the fin trade
(01/15/2013) Tens of millions of sharks and rays are killed each year to meet demand for shark fin, a delicacy across East Asia. But while the plight of sharks has gained prominence in international environmental circles in recent years, the decline in rays has received considerably less attention. A new film, Manta Ray of Hope, aims to change that. Produced by cinematographer, scuba diver, and marine conservationist Shawn Heinrichs, Manta Ray of Hope offers a look at the mysterious and magnificent world of the world’s largest ray, the manta ray. The film highlights both the threats mantas face as well as some of the people who are working to save them.

Jeff Corwin, an Emmy Award Winning TV host, has this week released Jeff’s Explorer Series: SHARKS, the first of a new eBook series, which Corwin likens to the 21st century version of an encyclopedia. The eBook is rich with video, images, and text. It is narrated by Corwin.

Animals dissolving due to carbon emissions
(12/03/2012) Marine snails, also known as sea butterflies, are dissolving in the Southern Seas due to anthropogenic carbon emissions, according to a new study in Nature GeoScience. Scientists have discovered that the snail’s shells are being corroded away as pH levels in the ocean drop due to carbon emissions, a phenomenon known as ocean acidification. The snails in question, Limacina helicina antarctica, play a vital role in the food chain, as prey for plankton, fish, birds, and even whales.
